During 21 years Swiss State Railway SBB ordered 276 samples of four axle electric loco Re 4/4 II. The four motor units develop 4700 kW and reach a maximum speed of 140 or 125 km/h depending on gearing. During the 1990 the locos were renumber for Re 420 and Re 421.
For traction of passenger and freight trains under 1,5 kV DC system French State Railway SNCF ordered 237 samples of four axle electric loco BB 7200. The locos develop 4040 kW and reach a maximum speed of 160 km/h. BB 7261 – 7263 are able to reach 200 km/h.
In 1956 State Railway of Portugal CP ordered 15 samples of four-axle electric loco Série 2500. The four motors speeded the loco up to 120 km/h.
In 1913 the Rhetian Railway (RhB) of Switzerland needed eight electric locos for their first AC line between Samedan and Scuol. The assembly had been done by SLM in Winterthur. The four driven axles are connected by side rods. Wheel arrangement is 2-8-2. With a tractive power of 1280 HP the loco reached a maximum speed of 34 mph. The last of the very successful locos had been taken out of service in 1984. In Swiss depot in Samedan 353 is still operated for fan trips
In 1913 Swiss narrow gauge Rhaetian railway RhB ordered seven samples of small electric loco Ge 2/4. The locos are equipped with side rods and deliver 228 kW. For additional tractive effort, RhB increased power up to 450 kW at two locos. So the maximum speed increased from 45 to 55 km/h.
For heavy freight and passenger service on famous Loetschberg-Bahn of Switzerland BLS ordered four samples of 2-6-6-2 electric locos Ae 6/8 in 1939. The motors develop 4400 kW and enable the locos to reach a maximum speed of 100 km/h.
In 1932 German Deutsche Reichsbahn-Gesellschaft DRG received 1st of 174 samples of four-axle electric loco E44. The four motors delivered 2200 kW and enabled the E44 to reach a maximum speed of 90 km/h. The reliable locos rested in service at DB until 1985, last DR locos quitted service in 1991. For electric service on Bavarian mountain line Freilassing – Berchtesgaden DRG ordered eight samples of electric E44.5. The four-axle four-motor loco developed 2000 kW and reached a maximum speed of 90 more…
In 1972 Swiss narrow gauge Railway Furka-Oberalp-Bahn FO received five four axle electric locos with luggage compartment. The four motor locos developed 1032 kW and reached a maximum speed of 60 km/h in adhesion drive and 30 km/h using rack drive.
Electric loco 111 of Deutsche Bundesbahn DB was purchased for fast passenger service on main lines. The four traction motors develop 3620 kW and enable the loco to reach 160 km/h. For consist use with heavy Intercity trains some locos received new pantographs. Some years ago all of the locos were given to DB Regio for push-pull operation.
In 2010 Siemens presented new Vectron family as successor for successful Taurus locos. The customer has the choice between four electric and one diesel electric versions. The locos develop 5200 kW (DC version) or 6400 kW (single AC, DC+AC version). Depending on gear ratio the locos reach a maximum speed of 160 or 200 km/h. For shunting service on non-electric tracks users can buy a Diesel Power Module with a 180 kW diesel motor.
